Daniel Roethlisberger 06a02f946a Always explicitly name the non-null arguments
Always explicitly name which arguments are non-null, even if all
arguments are non-null.  This is to avoid bugs where newly added
arguments are automatically non-null by accident, possibly leading to
optimisation errors.

This also fixes a few potential errors related to non-null arguments;
specifically it prevents the compiler optimising away a test for sni
being NULL in cachedsess_mkkey().
